; pictureFrame firmware build environments.
;
; Layout: shared sources at src/ root + panel-specific implementations at
; src/panels/{vendor}/v{N}/. Each panel/version gets its own [env:...] block
; that sets dimensions, pins, and panel-id via build_flags, and selects its
; driver via build_src_filter. New panel = new env block + new
; src/panels/{vendor}/v{N}/ folder + new data/{vendor}-v{N}/ folder. No
; surgery to existing envs.
;
; Old envs preserved as historical snapshots — re-flashing units in the
; field stays a one-line `pio run -e <env> --target upload` command.

; data_dir is single project-wide in [platformio]; PlatformIO silently
; ignores it inside [env:…] blocks. To route uploadfs to the right
; LittleFS payload per panel (waveshare73-v1 vs waveshare13e6-v1), each
; env wires in scripts/data_dir.py via extra_scripts, which overrides
; PROJECT_DATA_DIR from $PIOENV before SCons evaluates uploadfs.
; The project-level default below keeps tooling that runs outside a
; specific env (e.g. raw `pio run`) pointed at the 7.3" payload.
